An organism has the genotype AaDd. Which of the following options represent possible gametes from this organism? Select all that apply: Aa, Ad, ad, Dd, aD, AD.
Understand the Problem
The question is asking for the possible gametes that can be formed from the genotype AaDd. To determine the gametes, we need to look at the combinations of alleles from each gene (A/a and D/d) that can be passed on during reproduction.
Answer
Ad, ad, aD, AD
The possible gametes from the genotype AaDd are Ad, ad, aD, and AD.
Answer for screen readers
The possible gametes from the genotype AaDd are Ad, ad, aD, and AD.
More Information
For the genotype AaDd, each gamete receives one allele from each gene pair. By applying the principle of independent assortment, the possible combinations of alleles that can form during gamete formation are Ad, ad, aD, and AD.
Tips
A common mistake is to think that gametes can contain both alleles of a gene pair instead of selecting just one from each pair. Always ensure that gametes here have one allele for each gene locus.
